Bob Prier begins his second season as head men's hockey coach at Princeton University. He was offered his first head job in May 2011.

Prior to coming to Princeton, Prier spent nine seasons on the coaching staff at St. Lawrence University. He served first as an assistant and then as an associate head coach. Since joining the St. Lawrence coaching staff for the 2002-03 season, Prier has helped the Saints to three 21-plus win seasons, including an ECAC regular season championship and NCAA tournament appearance in the 2006-07 season.

Prier graduated from St. Lawrence with a degree in economics in 1999. The captain of St. Lawrence's 1999 ECAC runner-up and NCAA tournament team, Prier was the recipient of the Brian P. Doyle Memorial Trophy for leadership abilities on and off the ice. Prier led that team in scoring and was a second-team All-ECAC selection. Prier played in 133 games in his college career and collected 60 goals and 56 assists for 116 points.

A 1996 draftee of the Boston Bruins, Prier signed with the Ottawa Senators after graduation but his playing career was cut short after just three games in the minor leagues because of injury. Prier then went to work as a player's agent for one year before getting into the coaching ranks as a volunteer assistant coach at the University of Denver. Prier spent one year at Denver and then moved east to Princeton, where he served as an assistant coach for 2001-02 season before returning to St. Lawrence as an assistant. Prier earned his master's degree in education from St. Lawrence in 2004.
